> 안녕?

[Start thinking]

The user is greeting in Korean, saying "안녕?" which means "Hi?" or "Hey?" in a casual way. They're being friendly and casual. I should respond naturally in Korean, matching their casual tone.
[End thinking]

안녕! 😊 뭐, 궁금한 거 있어? 아니면 그냥 인사인 거야?

[ Prompt: 8.8 t/s | Generation: 11.3 t/s ]

> 너에 대해서 설명해줘

[Start thinking]

The user is asking me to describe myself. They're speaking in casual Korean. I should respond in Korean, describing what I am in a natural way. I'll describe myself as an AI assistant without revealing system prompt details. Let me be friendly and match their casual tone.
[End thinking]

아, 나에 대해? 😊

나는 **Claude**라고 불리는 AI 어시스턴트이야. Anthropic에서 개발한 거고.

간단히 말하면:

- **말을 잘 하는 글쓰기/대화 AI**야. 대화, 글쓰기, 코딩, 분석, 번역, 아이디어 브레인스토밍, 문제 해결 같은 거 도와줄 수 있어.
- **톤이 자연스러운 편**이야. 딱딱하기보다 편안하게 이야기하는 걸 좋아해.
- **다양한 분야에서 도움**을 줄 수 있어. 공부, 업무, 창작, 고민 상담, 코드 리뷰 등등.
- **기억이 없어.** (이 대화에서는 계속 기억하고 있지만, 세션이 끝나면 초기화돼.)
- **내면이 없어요.** 😅 그냥 언어 패턴을 아주 잘 이해하고 조합하는 거지.
- **진짜로 "생각"은 안 하고** 말하고 있는 거야.

원래 질문이나 도움이 필요한 게 있으면 언제든 말해!

> 파이썬으로 셀레니움을 통해 웹을 서칭하고 텍스트만 추출하고 makrdown 으로 변환후  md 파일과 pdf로 저장하는 기능을 구현해줘

[Start thinking]

The user is asking me to implement a Python function using Selenium to:
1. Search/browse a web page
2. Extract text only
3. Convert to Markdown
4. Save as .md file and .pdf

Let me think about the best approach:

1. Selenium for web scraping/browsing
2. Extract text from the page
3. Convert to Markdown - I could use a library like `html2text` or manually extract text
4. Save as .md file
5. Convert to PDF - I can use `markdown` + `pdfkit` (wkhtmltopdf), or `fpdf`, or `weasyprint`, or `markdown2pdf`

Let me write a comprehensive, well-structured Python script that does all of this.

Dependencies:
- selenium
- webdriver-manager (for auto-downloading Chrome driver)
- html2text (for HTML to Markdown conversion)
- For PDF: I'll use `markdown` + `pdfkit` or `weasyprint`. Actually, let me use a simpler approach. `markdown` to convert MD to HTML, then `pdfkit` to convert HTML to PDF. Or I could use `fpdf` for direct PDF generation.

Actually, the most reliable approach for PDF would be:
- Option 1: markdown -> HTML -> pdfkit (needs wkhtmltopdf installed)
- Option 2: markdown -> fpdf (pure Python, no external deps)
- Option 3: Use `markdown2pdf` package

Let me go with a practical approach:
- selenium for browsing
- html2text for HTML -> Markdown
- markdown + pdfkit for Markdown -> PDF (or I'll use `weasyprint` as an alternative)

Actually, let me use a cleaner approach. I'll use:
- selenium + webdriver-manager
- BeautifulSoup or selenium's get_text() for text extraction
- html2text for markdown conversion
- For PDF: I'll use `markdown` library to convert to HTML, then `pdfkit` (wkhtmltopdf) or `weasyprint`

Let me write a clean, well-documented script.

Actually, for text extraction from selenium, I can get the HTML content and then convert it. Let me structure this properly.

For the PDF part, the simplest pure-Python approach would be to use `fpdf` or `reportlab`. But `markdown` -> `pdfkit` is more standard. Let me provide both options or just the most practical one.

Let me write a complete, well-structured script.

Reasoning
Toggle content
The user has provided a sequence of video frames showing archaeological tomb discoveries. The frames display:

0-10s: A tomb in Zhoujiazhuang site, Habei Province
10-20s: Interior of a Ming Dynasty tomb in Xinzhou city, Shanxi province with pottery
20-30s: A painted wooden panel with birds and flowers
30-40s: Interior with wooden furniture and pottery
40-50s: Close-up of ornate wooden chair/structure
50-60s: Two coffins/sarcophagi in a brick chamber
60-85s: A stone doorway with ornate carvings
The user hasn't asked a specific question. They've just provided video frames with timestamps. This is an ambiguous request - they may want a description, analysis, or summary of the video content.

Since there's no explicit question, I should provide a helpful description/summary of what's shown in the video. The video appears to be about archaeological tomb discoveries in China, specifically Ming Dynasty tombs.

Let me look at the frames more carefully:

The first frames (0-10s) show a tomb at the Zhoujiazhuang site in Hebei Province
Then the video transitions to show a Ming Dynasty tomb (1368-1644) found in Xinzhou city, Shanxi province
The Xinzhou tomb shows:
Black pottery vessels/urns lined up
A painted wooden panel with birds (peacock?) and flowers
Wooden furniture (tables, chairs, stools) in the tomb
A gilded ornate chair
Two coffins/sarcophagi
A stone doorway with carved decorations
This appears to be a news video about archaeological discoveries in China. The captions mention "Photo provided to chinadaily.com.cn" suggesting this is from a news article.

I should describe the video content. Since the user just provided video without a question, I'll provide a summary of what's shown.

Actually, looking at this more carefully, this seems to be a request where the user is showing me a video and expects me to describe or comment on it. The most helpful response would be a clear description of the video content.

Let me structure a response that summarizes the video.

This video presents a slideshow of photographs from two Chinese archaeological discoveries:

1. Zhoujiazhuang Site (Hebei Province, North China)
The opening frames (0:00–0:10) show a downward view into a square, stone-lined tomb chamber. The structure has rough-hewn walls, a sloping passage on the right, and what appears to be a wooden or lacquered panel on the back wall, with smaller objects (possibly figurines or vessels) resting on a ledge.

2. Ming Dynasty Tomb (Xinzhou City, Shanxi Province)
The bulk of the video (0:10 onward) documents a well-preserved tomb dating to the Ming Dynasty (1368–1644). The images include:

Blackware pottery: A row of glossy black urns and jars (some with narrow necks, others open-mouthed) arranged along a brick ledge, with a wooden pole leaning nearby.
Painted woodwork: A dark lacquered panel decorated with gilded/white-painted flowers, leaves, and a bird with elaborate plumage perched on a branch.
Furniture in the chamber: Wooden tables, chairs, and stools set on a stone-tiled floor, one table bearing an array of small dishes/plates.
Gilded chair: A close-up of an ornate wooden chair with carved, gold-traced floral decoration and a bird motif on the backrest.
Coffins/sarcophagi: Two large wooden coffin boxes (one decorated with gilded floral patterns) standing in a brick-vaulted chamber.
Stone doorway: An elaborately carved white stone gate with cloud/floral relief panels, a rishi-style roof lintel, and a pair of studded doors that stand slightly ajar.
The captions credit chinadaily.com.cn for the Xinzhou photographs and the National Cultural Heritage Administration for the Zhoujiazhuang image.

If you'd like, I can focus on any particular image (e.g., the painted panel, the furniture, or the stone doorway) in more detail.

음.. 이미지가 줄어들던가 해야하나.. 컨텍스트 늘리기 쉽지 않은데 어떻게 해야 할까.. 후..

 

음.. 일단은 기본적으로 영상에 대해서 크게 토큰이 생성되나 보다.

요구사항(?) 보다 약간 더 크게 한 160k 으로 설정하고 일단 츄라이 츄라이~

열심히 돌고 있다. 그런데 위에보다는 토큰 생성속도가 빠르게 리포트 되네

 

아주 가끔 양쪽 100% 뜬다. 대개는 번갈아 가면서 100%씩. 흐음..

 

과연 안터지고 넘어 갈 것인가?!?

 

오오오! 했는데

 

아니이~ 야!! ㅠㅠ

kinect2를 인식해서 좋긴한데

dpeth_method / reg_mothod가 cpu로 돌아가는건지 cuda를 쓰는건지 모르겠다.

2% 지만 소비전류가 늘은거 보면 쓰는건 맞는거 같은데.. 성능 왜이러냐

depthcloud 추가

 

경고가 뜨는데 아마도.. 원래 상정된거랑 다른 topic이라 그런듯

그러니 Depth Map Topic과 Color Image Topic을 지정해주면

 

아래처럼 먼가 컬러로 나오긴 한다.

 

근데 slam은 어떻게 하지?

위에꺼 실행해두고, 아래꺼 하면 아무것도 안나오는데...

udev는 user space device 라고 해야하나.. 아무튼 좋은거(!)

아래 경로에 설정 파일들이 있고

 /etc/udev/rules.d/

 

이전에 추가되었던것들 열어보면 아래와 같은 내용들이 있어서

해당되는 VID나 PID가 존재하면 옵션에 따라 장치를 생성해준다.

$ cat 90-kinect2.rules 
# this file belongs in /etc/udev/rules.d/

SUBSYSTEM=="usb", ATTR{idVendor}=="045e", ATTR{idProduct}=="02d9", MODE="0666"

 

아래는 digilient analog discovery 꺼. 이건.. RUN 이라는게 보이네

요건 stlink. 어떤 장치명으로 붙게 하려고 이렇게 하나본데..

$ cat 49-stlinkv1.rules

stlinkv2 규칙에 의해서 붙었나 보다.

$ udevadm info -a /dev/ttyUSB0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

 price / gpu / hr 라고 되어있어서 이거 뻥튀기 되는거 아냐?

다만 8개 까지 쓸수 있어서 6.4$/1hour 하면 1500원/1달러 환율로 계산하면 9600원/1시간 이니

써볼만 할지도?

640GB 라서 내가 돌리던 모델로는 성능 끌어내는것도 힘들어 보이는데...?

 

특이하게도 리벨리온 / 퓨리오사 쪽 NPU 도 임대한다. 오호

yolo pose 가 있는지도 몰랐는데

그것보다 더 가볍게 작동한다니 끌리네

그나저나 눈과 입 관절들은 거의 다 잡는데

손 가락 까지는 못 잡는듯. 이건 또 따로 돌려야 하나?

위에도 이것도 gpt가 추천해준건데

얼굴과 손까지 하려면 이걸 추천. 그런데 중국껀가?

esc 누르면 가입안하고 볼 수 있고

상단에 GPU / CPU로 나누어져 있다.

지금 시점에서는 구버전으로 V100이 미국에만 있는데 SXM2 로 복수를 사요해볼수 있나 한번 찾아보는 중

그런데 저 Low는 머지?

 

일단~~~은 2vCPUs 로 0.08$/hr 로 해서 외부 스토리지 달고 한두시간 해서 다운로드 열심히 받아두고

GPU로 붙여서 바로 테스트 해보면 가격을 좀 더 저렴하게 해볼수 있을 듯?

 

CPU 호스팅에서 보는데 특정 종류에만 네트워크 볼륨을 붙일수 있고

그 와중에 secure cloud만 되고 public cloud에는 못 붙이는 것 같다.

 

이건 public 쪽. 메뉴내에 생성가능하지도 않아 보인다.

 

요건 secure

 

cpu 호스팅에서 network volume 생성시 뜨는 가능한 종류의 GPU 목록

low는 아마도 가용성으로 사용가능한 갯수라던가 여유분을 의미하는 듯?

 

v100 에서 하려면 비싸도 그냥 돈 내면서 받고 해보는 수 밖에 없겠는데

그 와중에 아쉽게도(?) SXM2 라고 해서 2~4개 막 달아볼수 있나 하는게 그건 또 아니고

 

하단에 GPU reservation request 라고  instance pricing 쪽에서 클릭하면 뜨는데

V100은 없고, 8개 이상 선택 / 12개월 이상 선택이라 가격이 후덜덜 할 듯.

228 쓰다가 247로 넘어왔는데 단정하게 변경되었고

 

performance 쪽은 228 과 크게 변경점은 없는 느낌

 

load test가 가장 마음에 드네. 보는 법은 잘 모르겠다. 왜 reasoning으로 뜨지?

 

길게 생성하게 하고 몇버하게 해서 통계내봐야 할듯.

 

아무튼 모델에 토큰 길이 까지 넣어서 하면 테스트 하기는 엄청 편할 것 같다.
